Knee Type & Bridgeport Mills

The drilling and milling head on these knee mills features a quiet V-belt drive operation and infinitely variable spindle speed control, paired with automatic spindle sleeve feed (3 steps with micrometer depth stop) for precise and efficient milling. The spindle braking is controlled via a simple hand lever for ease of use.

KAAST’s Bridgeport mills are built to last, with a high-quality heavy-duty MEEHANITE cast iron base and all guideways coated with Turcite B® for maximum durability. The XYZ slideways, table, and T-slot are hardened and ground for long-lasting wear resistance. The high-grade casting is annealed and stress relief for high rigidity, making it perfect for even the toughest milling jobs. Box ways on Y and column ensure smooth and precise movement, while telescopic steel covers protect the slideway and ball screw from dust and coolant. Plus, semi-guarding is standard with optional full guarding available on the knee mills.
